Answer:

In order to maximize the last equation we can derivate the function in term of x and we got:

And setting this derivate equal to 0 we got:

And solving for x we got:

And for this case the value that maximize the profit would be x =95 and the corresponding profit would be:

Step-by-step explanation:
For this case we have the following function for the profit:

And we can rewrite this expression like this:

In order to maximize the last equation we can derivate the function in term of x and we got:

And setting this derivate equal to 0 we got:

And solving for x we got:

And for this case the value that maximize the profit would be x =95 and the corresponding profit would be:

I would round them so it would be 500 divided by 20
The answer should be close to 25
Tan(58)=10/x
x=10/tan(58)
x= 6.2
Yes, 1/4 of 8 is equal to two.
1/4x8=2
Hope this helps! :)
